I saw this while reading IGN's article last night. He said <3 hours for extensive use and <5 hours for non extensive use. So if you are playing ZombiU and have to use the game pad at all times, you can probably only play for about 3 hours, assuming you have it at 100% charge. The game pad always takes 2.5 hours to get a full charge.

However, the Pro controller has an 80 hour charge...Which probably means ~30-40 hours.

Saw my first TV spot for the Wii U last night. It was the commercial for the system and NSMB U. I thought they did a good job of showing not only how fun it is, but also that its a NEW system. SO if theres any confusion (which im sure there will be) those people are just ignorant. They also highlighted how you can play games on the gamepad while someone else (Mom) watching TV (Dancing with the Stars)

The only way to play Nintendo games is to buy Nintendo consoles. It doesn't matter to people on the VGF if they are just buying a beefed up PS3. I love my PS3, why not get one that plays Nintendo games too!

I am in a similar boat. If I get 2 straight hours of play without interuption from the wife and/or kids.... color me happy. Not too mention I am sure the tablet can be charged and played at the same time for those with more time than I apparently have.
